Answer:
B.(-6,-1)
Step-by-step explanation:
Radius is the distance between the center and any point on the circle.
r=distance =√((x2-x1)² +(y2-y1)²) =√((5-(-3))²+(-7-(-1))²)=√(64+36)=√100 = 10
r=√100
Equation of the circle , where (h, k) coordinates of the center of the radius.
(h,k)=(5,-7)
(x-h)² +(y-k)² = r²
(x-5)² +(y+7)² = (√100)²
(x-5)² +(y+7)² = 100
Answer:
The required expression would be (a-4)x + (9-b)
Step-by-step explanation:
Given,
In the triangle,
Base = 4x + b,
Side = ax + 9
Since, Side - base = 



That is,
The base is (a-4)x + (9-b) shorter compared to the side.
Answer:
C
Step-by-step explanation:
because to solve it you are seeing which number divises 52 to get you 13
so using the inverse you just need to use multiplication
-7(-8) = 56 [multiplication of two negative numbers gives a positive number]
